Video of a third grade number talk: https://www.teachingchannel.org/videos/third-grade-mental-math?fd=1# Number Talks are implemented during the "warm-up." This mental math routine is extremely important for helping students develop/solidify strategies based on place value and decomposition of number. The problems and numbers use in the number talks are designed to elicit certain strategies that focus on number relationships, place value, and properties. As students explain and defend solutions, they will have an opportunity to collectively reason about solutions and to make connections between key mathematical structures. These number talks are a key component for students to develop flexibility with number.
These routines bring to life these practice standards:
Construct viable arguments and critique the reasoning of others
Look for and make use of structure
Look for and express regularity in repeated reasoning
The number talks get steadily more difficult as the weeks progress. These routines have been adapted from the book, Number Talks, Helping Children Build Mental Math and Computation Strategies, by Sherry Parrish. We highly recommend purchasing this resource for grades 2-5.
